Occultations of stars by solar system objects. VIII - Occultations of catalog stars by asteroids, planets, Titan, and Triton in 1990 and 1991
Predictions are given for occultations of catalog stars by asteroids,planets, Titan, and Triton in 1990 and 1991. The predictions are basedon a computerized comparison of the occulting bodies' ephemerides andnine major star catalogs. The search is complete for all numberedasteroids whose angular diameters exceed 0.08 arcsec during the searchyears. Preliminary ground tracks are shown for the more favorableoccultations.

Photoelectric observations of lunar occultations. XII
Occultation observations of 414 events observed between 6 July 1979 and4 September 1980 with the 0.76-m telescope of McDonald Observatory arereported. Timings and data on double stars are given. Angular diameterinformation in six cases is included. The stars concerned with their runnumbers are: SAO 161754 (5270); 94027 (Alpha Tau) (5319, 5381, 5454);159370 (Gamma Lib) (5325, 5571); 162413 (43 Sgr) (5332); 97472 (3 Cnc)(5414); and 93955 (Theta Tau) (5445).
